Wang, Z, Zhao, L, Huang L., Hong A., Yu C., Xiao Q., Zou B., Xin J., Zhang L., Zhang J., Wang Y., Jia P. (2020) Traffic-related environmental factors and childhood obesity: A systematic review and meta-analysis. Obesity Reviews. 10.1111/obr.12995

This study reviews existing research on the relationship between traffic‐related environmental factors and childhood obesity. Of 16 studies of weight‐related behaviours, significant associations are reported in 11 out of 12 studies on traffic flow, 5 out of 6 studies on traffic safety, one study on traffic pollution, and one study on traffic noise. Among 23 studies of weight‐related outcomes, significant associations are reported in 6 out of 14 studies on traffic flow, 7 out of 10 studies on traffic pollution, and two out of five on traffic noise. Our findings show that long‐term traffic pollution is weakly positively associated with children's BMI growth, and traffic flow, pollution, and noise could affect weight‐related behaviours. Associations between traffic density and noise and weight status are rather inconclusive.

This study examined the relationship between construction activities and noise annoyance and tested whether this relationship is stronger after working hours. Data were drawn from a historical inventory of major development projects and 2 million records of crowdsourced citizen complaints data (311 calls) in Vancouver, Canada from 2011 to 2016. Results show that neighborhood noise complaints were significantly associated with major constructions. A significant interaction effect was also found between construction activities and after-hours reporting. To our knowledge, this is one of the first studies to empirically show the adverse effects of urban development on noise annoyance. The results imply that existing noise bylaws may not be effective in restricting construction activities at night and during sleeping hours, which may cause adverse health effects.

Hong, Andy. 2019. Effect of mode shift from car to light rail on personal exposure: A controlled experiment. Atmospheric Environment, 196: 53-65. 10.1016/j.atmosenv.2018.10.004

This paper investigates to what extent mode shift from car to LRT can reduce personal exposure to PM2.5, BC, and UFP. Simultaneous measurements on LRT and automobile were conducted under four plausible commuting scenarios in Los Angeles, California from October to November in 2014. The results indicate that modal difference in commuter exposure between car and LRT is, in large part, driven by ventilation status and travel microenvironments. Other factors, such as roadway type, vehicle fan strength, vehicle speed, and vehicle age, are likely to influence the modal difference in a more subtle way. Results inform future research and policy about the importance of incorporating ventilation and traffic microenvironments for assessing the health effects of a mode switch from car to LRT.

New light rail transit and active travel: A longitudinal study

Hong, Andy, Sallis, James F., King, Abby C., Conway, Terry, Saelens, Brian, Cain, Kelli, Fox, Eric, Frank, Lawrence. 2018. Linking green space to neighborhood social capital in older adults: The role of perceived safety. Social Science & Medicine, 207: 38-45. 10.1016/j.socscimed.2018.04.051

This study examines the moderating effect of perceived safety on the association of green space with neighborhood social capital in older adults. Data were drawn from 647 independent-living seniors who participated in the Senior Neighborhood Quality of Life Study in the Seattle/King County and Baltimore/Washington DC region. The results suggest that certain green space elements, such as natural sights, may be beneficial to neighborhood social capital of older adults. However, other types of green space, such as parks and street trees, may be less advantageous to older adults who perceive their neighborhoods as unsafe for pedestrians. Findings highlight the importance of pedestrian safety in examining associations of green space with neighborhood social capital in older adults.

New light rail transit and active travel: A longitudinal study

Hong, Andy, Boarnet, Marlon G., Houston, Douglas. 2016. New light rail transit and active travel: A longitudinal study. Transportation Research Part A, 92: 131-144. 10.1016/j.tra.2016.07.005

This study investigates the before-and-after impact of a new light rail transit line on active travel behavior. Using panel data, we found that living within a half-mile of a transit station was associated with an increase in walking and physical activity for participants who previously had low walking and physical activity levels. The results were opposite for participants with previously high walking and physical activity levels. Future policy and research should consider the possibility that sedentary populations may be more responsive to new transit investments, and more targeted “soft” approaches in transit service would be needed to encourage people to make healthy travel choices.
